> The Internet Engineering Task Force (IETF) standards-track RFC 6762 (February 20, 2013) reserves the use of the domain name label local as a pseudo-top-level domain for hostnames in local area networks that can be resolved via the Multicast DNS name resolution protocol.[1] Any DNS query for a name ending with the label local must be sent to the mDNS IPv4 link-local multicast address 224.0.0.251, or its IPv6 equivalent FF02::FB. Domain name ending in local, may be resolved concurrently via other mechanisms, e.g., unicast DNS.
